Discovered in Greenland in the late 1890’s, hackmanite is named for Finnish geologist Victor Hackman. It is a rare occurrence to find gem-grade hackmanite; at best, most crystals are translucent. Hackmanite is the light pink to pale violet variety of sodalite. It is a particularly unusual gem because it exhibits a special optical property known as “tenebrescence,” a type of reversible photochromism. This feature allows the gems to temporarily change color when exposed to different light forms. While hackmanite gems are usually pink to violet, the color quickly fades to gray or greenish-white in sunlight, and will slowly return to the original color after changing the light. Its tenebrescent property makes hackmanite a prized mineral for collectors.

¿Por qué los usuarios se superan a sí mismos?
Cuando se realiza una oferta, esta es la cantidad máxima que un usuario está dispuesto a ofertar por el producto. Luego, nuestro sistema ofertará automáticamente en nombre de ese usuario, aumentando gradualmente la oferta para mantener su posición como el mejor postor, hasta el máximo especificado.
Cuando hay un ícono que indica "Oferta automática", significa que nuestro sistema está realizando ofertas activamente para el usuario en función de su oferta máxima. Esto puede parecer como si los usuarios se estuvieran superando a sí mismos, pero es simplemente el resultado de que el sistema actualiza la oferta para reflejar el límite máximo de los usuarios.
